Yes, the amount of contact with the ground should be pretty much the same.
Even if the amount of wheel touching the ground was reduced, wouldn’t there be increased pressure on the places still touching? Same weight distributed to an even smaller area. Actually, there might be even more weight with bigger and heavier wheels and whatever is needed to accommodate them.

My school district does teach typing, or at least keyboarding, in the elementary schools. I don’t think they teach a lot of the things I remember from typing class like “how to format a business letter” – but I think on a “life skills” level that’s a lot less important than being able to put text into the computer with basic speed and accuracy, especially since fixing a mistake involves moving pixels around instead of white-out or that alleged ink eraser. I don’t know Daughter’s exact speed, but I’d guess she’s closer to 50-60 wpm than 30-40.
